发布作者：微思网络 发布时间：2022-08-09 浏览量：0次
备注：orcl1是一套oracle RAC 集群中的一台服务器 主库为归档模式 主库： 启用强制日志模式（mount 状态下修改） 主库： Force_logging 为YES 代表数据库是强制日志模式。 配置standby 日志文件 主库： 配置监听（主库和备库） 使用netca配置监听。 下图是监听配置后的结果，监听正常。 主库：RAC 不用单独配置监听 备库：配置DG的时候，备份的数据库还无法open,所有要配置静态监听/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora 启动监听：lsnrctl start 配置tnsnames文件(主库和备库) ORCL_PRI 为主库的连接信息，orcl_std为备库的连接信息/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora 主库： 备库： tnsping （主库和备库） 确认主库和备库是否联通 主备库：tnsping ORCL_PRI tnsping ORCL_STD 创建pfile并修改。 主库： 创建pfile ,修改pfile,生成spfile,并以spfile 启动数据库 备库： 创建相应的路径： 配置密码文件 将主库A的密码文件复制到备库和 主库B 备库创建spfile ,并启动到nomount 使用RMAN连接主备库，复制数据 打开备库，并开始同步数据Select log_mode from v$database;SQL>select force_logging from v$database;
